This project demonstrates how to implement the CQRS (Command Query Responsibility Segregation) pattern in an Angular application using modern architectural practices.
CQRS is an architectural pattern that separates write operations (Commands) from read operations (Queries). Instead of handling all business logic in a single flow, CQRS divides responsibilities into two independent parts:
- Commands → Responsible for changing application state
- Queries → Responsible for reading and retrieving data
This separation improves:
- Scalability
- Maintainability
- Testability
- Clear separation of concerns
In Angular, CQRS can be implemented very effectively with NgRx, since NgRx naturally provides a predictable state management flow through Actions, Effects, Reducers, and Selectors.
In this project, we apply CQRS principles using NgRx:
- Commands are represented by Actions that trigger state changes
- Effects handle side effects such as API calls or async operations
- Reducers update application state based on command results
- Queries are implemented using Selectors to efficiently retrieve state
The goal of this repository is to showcase how Angular and NgRx can be combined to build a scalable CQRS-based frontend architecture suitable for enterprise-level applications.
This project is intended for developers who want to learn how to structure Angular applications using advanced architecture patterns beyond traditional component-service design.
